How to Build Structured Agent Flows Using the Sequential Node
What Is the Sequential Node?
The Sequential Node is a core building block in Agent Studio that enables you to execute a series of actions in a fixed, predefined order. It serves as the execution engine for your agent, running each step sequentially from top to bottom without relying on dynamic decision-making. This node is ideal for predictable workflows, such as gathering user details, making API requests, or performing a chain of operations.
Key Benefits
Using the Sequential Node offers several advantages:
- Executes steps in a clear, predefined order
- Ensures predictable and repeatable outcomes
- Simplifies flow design by grouping multiple steps into a single node
- Enables structured data collection
- Reduces complexity compared to managing multiple separate nodes
Core Elements
Processing Nodes
Each step inside a Sequential Node is defined by a processing node. These nodes represent individual actions—like capturing input, making an API call, or generating content—that execute in sequence.
Step Execution Order
The Sequential Node runs processing nodes in the order they are added, from top to bottom. Each step must complete before the next begins, ensuring a controlled and predictable flow.
Processing Node Types
You can use various processing node types within a Sequential Node to suit your needs:
- Capture Information: Collect user input like email, phone number, or selections.
- Actions & API: Perform operations or send data to external systems.
- AI Generation: Generate text, images, video, or audio content.
How to Configure the Sequential Node
Before using the Sequential Node, ensure a trigger is configured to start the agent. Within Agent Studio, add a Sequential Node to your flow and begin adding processing nodes to define each step. Configure each processing node according to its specific purpose—for example, set validation rules for input nodes or define API endpoints for external calls.
Frequently Asked Questions
When should I use the Sequential Node?
Use it for workflows that require a fixed, step-by-step sequence, such as data collection or integration tasks, where predictability and control are essential.
Can I change the order of steps after creating the node?
Yes, you can reorder processing nodes within the Sequential Node by dragging and dropping them into the desired sequence.
How do I handle errors in a Sequential Node?
Each processing node can be configured with error messages or validation rules to ensure data quality and flow integrity.
